How about you start with cleaning that engine bay dude?
Me no expert but that motor is not well known as a base for performance mods since it`s a 3stage vtec-e designed for economy. There are some info on Turboing this engine on the net but IMHO that`s a waste and asking for trouble. It i were you I would invest on other stuff (light weight alloys with good rubber, suspension tune to improve handling, etc.. ), leave that engine as it is an be happy.
If you are really serious and got the money, do a "K" series motor swap (there are high output "B" series motors as well, these are mainly DOHC, but this series is quite old, not sure about availability of a good specimen).
P.S. Whatever you do, don't just throw in high flow filters and performance exhausts and shit without doing a proper ECU remap. Without a remap, chances are that you`ll might even get less performance with those.
